  • Atom probe tomography can image chemical composition at the nanoscale, but our understanding of how it images voids, or empty spaces, is still lacking. Here, the authors combine atom probe tomography, scanning transmission electron microscopy, and field-evaporation theory to show how voids are imaged and subsequently measured.

  • The authors report the unification, in a single instrument, of two microscopy instruments: Atom Probe Tomography and Transmission Electron Microscopy. This instrumental outcome opens original perspectives for 3D atomic scale microscopy.

  • The information on chemical and bonding states in atom probe tomography is typically not resolved in one of the three dimensions. The authors devise a data analysis protocol to process the mass peak shape, quantifying the ion energy loss associated to the field evaporation and retrieving the original bond framework of the atoms on the surface.
